Industrial solid waste-based cementing material and concrete material
The invention discloses an industrial solid waste-based cementing material and a concrete material in one embodiment. The industrial solid waste-based cementing material comprises high-titanium blast furnace slag powder, converter slag powder, gypsum powder and ash; the specific surface area of the high-titanium blast furnace slag powder is 550m < 3 >/kg-600m < 3 >/kg. The industrial solid waste-based cementing material comprises high-titanium blast furnace slag powder, converter slag powder and gypsum powder, as blast furnace slag is high in titanium content and poor in activity, the high-titanium blast furnace slag powder with the specific surface area being 550 m < 3 >/kg-600 m < 3 >/kg is adopted, the contact area of the high-titanium blast furnace slag powder and water is enlarged by increasing the specific surface area of the high-titanium blast furnace slag powder, and the high-titanium blast furnace slag powder is made to be more uniform. The high-titanium blast furnace slag powder obtained after ore grinding generates lattice distortion and local damage, meanwhile, various lattice defects are formed, internal energy is increased, and therefore the activity of the high-titanium blast furnace slag powder is improved. According to the industrial solid waste-based cementing material, the specific surface area of the high-titanium blast furnace slag powder and the activity of the high-titanium blast furnace slag powder are increased through ore grinding, so that the industrial solid waste-based cementing material containing the high-titanium blast furnace slag powder has enough reaction activity and can be used for preparing concrete.
本发明公开了一实施方式的工业固废基胶凝材料和混凝土材料，工业固废基胶凝材料包括高钛高炉渣粉转炉渣粉、石膏粉和灰分；所述高钛高炉渣粉的比表面积为550m3/kg~600m3/kg。本发明的这种工业固废基胶凝材料包括高钛高炉渣粉、转炉渣粉以及石膏粉，由于高炉渣含钛量高，活性较差，本发明中采用比表面积为550m3/kg~600m3/kg的高钛高炉渣粉，通过增大高钛高炉渣粉的比表面积来扩大高钛高炉渣粉与水的接触面积，加快高钛高炉渣粉水化反应速率，磨矿后得到的高钛高炉渣粉产生晶格畸变和局部破坏，同时形成各种晶格缺陷，导致内能增大，由此提高了高钛高炉渣粉的活性。本发明的这种工业固废基胶凝材料通过磨矿增大高钛高炉渣粉的比表面积和高钛高炉渣粉的活性，使得包括高钛高炉渣粉的工业固废基胶凝材料具有足够的反应活性，可以用于制备混凝土。
